Abstract

In the framework of the relativistic independent quark model the parameters of the QCD-motivated static potential and the quark masses are calculated on the basis of the $1^{--}$ meson mass spectra. The value of the confining potential coefficient is found to be ( $0.197 \pm 0.005) G e V$ {}^2 $. f or q u a r k - an t i q u a r k in t er a c t i o nin d e p e n d e n tl y o n t h e i r f l a v o u r s .
